# Remarks

Recall that the percentile is the value such that at least `interest`-percent of the data set items are less than or equal to this value, or equivalently if at least `(100-interest)` percent of the items are greater than or equal to this value.

Remarks:

1. The `50`-th percentile is the measure of centrality of a data set known as the median. The median can also be evaluated using Median.
2. The `25`-th, `50`-th, `75`-th percentiles are often referred to as the `1`-st, `2`-nd (median) and `3`-rd quartile respectively. The term quartile refers to the fact that these three values will roughly divide the data set considered into four equal parts.
